2strokenut's 5.3hr TPI 300 review

Recommended Posts

Hi

I've hit the magical 5.3hr mark this past weekend with a few rides and some time to gather my thoughts on my 2019 300TPI, as well as some questions.

Stats:
6'3" 200 30A rider
Previous bike: 17 300XC, head, ported, see sig

Some background:
I had TFCC surgery on my wrist on August 1st and got my cast off about 2 weeks ago. Prior, I had not been riding much since my wrist really hurt from a rather hard fall back in April. I'm a little out of shape at the moment.


I've decided to try out my TPI bone stock to get a feel of how KTM has set up the fuel injection and actually know where I can improve before making any changes. The only mod I have done is transfer my KYB conversion forks to the bike and sold the Xplor forks. Rear shock is stock. This is also my first real PDS bike. I had an 08 125sx years ago but didn't ride it much.

First ride last weekend (doing sweep for the race we put on):

-Bike feels lean on the stand but while riding feels like a perfectly jetted carb bike
-Much less power, very smooth and manageable but feeling the need to shift more where as on my 17 you really don't care what gear you're in. It will pull it.
-Bike felt balanced and seemed to behave just like my linkage bike
-Wrist was still stiff so did not push it too hard
-I finished the weekend a little disappointed in the bike because it was such a drastic change in power from my 17. It didn't want to pull 2nd or 3rd where I wanted it to.

2nd ride yesterday (my trails behind my house, tight, rocky, hard enduro type stuff)

-Power was not an issue riding this stuff
-Bike felt really good and gave confidence.
-I'm beginning to see that the stock tires, mostly front, are fairly terrible
-Bike seems to sip fuel
-Took my poor dad on his 350 with me so we couldn't do anything too gnarly



3rd ride today normal trails I'm used to Sycamore creek area in AZ: 

-Really tried pushing the bike and myself harder to get a feel for the suspension and power.
-The lack of power didn't really bother me today as much as it did last weekend
-I strava'd the ride to see how I did on trails where I know what pace I can do comfortably
-I did feel like the front end was very light and skiddish but I think it has to do with the terrible front tire. On the decomposed granite we ride it was scary today. I normally run bibs and a parker DT in the front, IRC M5B evo in the rear
-3rd gear seemed to be reasonable for most of what we did today and didn't seem to beg me to downshift much. 2nd seemed to work fine with a little clutch work
-Idle seems to be just a tad low
-The PDS honestly seems to work fantastic. There are some trails with those small whoop/bumps that will kind of beat you to death and the PDS works amazing on that stuff, so much I'm confused because I feel it shouldn't work as good as my linkage bike.
-Power felt inadequate once we were in the washed where I could open her up.


Thoughts after today:

This is without a doubt the best stock bike I've ever ridden. It feels perfectly jetted the entire time with no hiccups in the power. In places where I know it's lacking power it will still pull nicely with a little clutch work. Full throttle, no bog, no problem. The response in power is instantaneous, as in, as soon as you turn the throttle at all you feel it make power. No carb bike has this feel. It was my first thought when I tried an FI 4t bike. As soon as there is input on the throttle its cruising. No lag time. Crazy response and crazy low lugging ability.

I can't say anything about the Xplor forks but I think if you have the fork set up for your liking this is easily the best 2-stroke product KTM has ever put out. You need to do literally nothing to the motor to have a good time. I had a blast today. In fact, I have had a KOM on one of the trails out here for the last year and a half. If you ride this spot you know which trail I'm talking about. Fast and flowy, gets technical in some spots, nice sandy turns, just an absolute blast. A friend of mine took my KOM about a month ago and I decided to just cruise it today to see where I was at. Turns out, I ended up about 15 seconds off my best time and the fastest person all day to hit it. All on a stock bike and stock shock and a front tire that scared me to death half the time. It's deceptively fast and tractable.

We did about 25 miles and used about .8 gallons ending up at around 31mpg. If that sounds low, that's better than my Lectron 17 would have done and used less fuel than the 350 on our ride.


Future mods and testing:
RK Tek head- Would love just a little more power everywhere and some more juice for the sand washes.
Red spring- I'm a red spring guy and gotta try it on this
I'm ordering a DEP off road pipe to try and after watching straight rhythm I need a PC shorty in my life as well.

Questions:
Bike seems to die with quick throttle at idle. Not sure I want to mess with the idle, have any of you guys run into this? However, letting this thing warm up idling without touching the throttle is the way to go. If it's not warm it will need clearing out like a regular 2t. Let it idle for a few minutes and it literally need no clearing out and run perfect. Crazy.

Some non-engine things I've added or will add once I get a chance:
Antigravity restart battery
AXP skid plate
Topar front disc guard
Rear disc guard
Protech wrap around fork guards
swingarm guards
chain guide protector
Changed out the plastic
Radiator fan with relay kit
front and rear bibs
Flange guard
JD tuner (when needed)

The tires, front especially, suck. Just beating them down and looking forward to something else. Mine does not appreciate being ridden before it warms up for a bit either. I really like the xplor forks. I came from a SSS WR450 and these feel pretty good. Maybe not as great when doing endless high speed whoops but still good.  The bike is indeed deceptively fast! The idle stall thing has happened to me. It idles too low and the factory idle adjustment is a joke, you don't lean an engine out to make it idle faster!! Slavens idle screw can fix that. 

Interested to see how the power valve spring effects your bike. Not supposed to even adjust the stock spring setting without a tuner, haven't heard of anyone messing with them. 

I actually prefer the ultra smooth/mild power delivery so I'm not looking to change it up. It's pretty strong up top. Mine consistently pulls on our YZ250 even though I weigh 50 pounds more than my son. He can even get a bit of a jump and this XCW reels him in. Not topped out either, both bikes are still banging gears.

Correct me if I'm wrong, is the Slavens thing a way to adjust the cable?

 

There a few guys that have put in the red spring with no issues. The reason I'd like more power is I run a series here in AZ that has a lot of varied racing. Fast single track, rocks, deep sand whoops and washes and want a do all bike. That's exactly what my 17 is and we'll see how the 19 does.

The slavens screw actually operates the throttle body blade. I have found that my '19 has a bunch of power even if it's not really forthcoming with it. It requires aggressive throttle inputs to bring it to life. Maybe a different throttle cam would help?

Good write up.  I was at sycamore sunday, you held me up all day long on that TPI!!!    ;)  

 it has to be great to just get a bike and ride it.  Mine was a PITA for quite a while, granted a good measure was my fault but never would have happened on a FI'd bike.

I am finally selling my yz 250 with those sweet KYB's    I love to keep them for my 18 but I have to say my Xplor's are better in the slow stuff vs kyb.  But KYB is more versatile.

Haha, did you have Strava going all day?

 

It's amazing for KTM to nail it so well the first time. There is always room for improvement, however. I'm still going to buy the PowerCdi as soon as it's available and get an RK head. I think you'd like the bike very much as is. I have a set of KYBs off an 09 YZ450 if you're interested...

lol, dont get me started on the strava users out there.  ;)  

If they change some things on em I'd consider one.  Right now I absolutely love my 18.  Your KYB is temping but if I do anything it'll be inserts.  I forget the name.   del sall  or something...you know what I'm talking about.  haha.  But like I said my tweaked xplor is unreal.  I had Stillwell do some experimental deal on them that I think is their mainstream offering now.

I'll sell them for 500 bucks. Perfect condition. Dal saggios are like 1700.

 

What would they need to change?

Hmmm.  I dont think TBT will reuse internals if I recall right.  He buys all new stuff and I dont know how to do it myself.  500 for KYB is a pretty good deal.

A better thought out pump in the tank- easier to swap out or an external pump or maybe just watch the process of swapping one out in the field.  Maybe it isnt as bad as I think.   Electrical system that doesnt require a battery similar to my FI'd  450 where a capacitor would start it which takes no space and weighs 2 ounces or so.  Trim some of that weight, that big controller would be a good place to start.

I've said it before, TPI and FI gets you an unreal smooth running motor, you smile just listening to it.  I could listen to my 450 forever.

Getting 31mpg is very appealing if you were going race pace in sycamore.  That has immense appeal given that's another 15+ miles I can go on a tankful.  But I have heard from others that were disappointed that they didnt get more.  Wonder if it's a mapping thing?  I put the euro map in my FI'd 450 and got no better mileage then my carb'd 450.

I know I will sound like a global warming fruit cake instead of the agnostic I am on the issue, but I REALLY hate gas dripping on the ground from the carb.  It bothers me.  So another advantage for TPI.  So until I go TPI I will continue to try not to fall.  ;)

I have a set up showa's with the shims, and honda wheel.  It worked amazing but if I do anything it will be inserts.  Like I said the xplors with stillwell intervention is the best thing I've ever owned for slow tech up to moderate speeds.  After that it's pretty good but not KYB.  I also have a fox shock on it that is just as buttery as the forks.

Congrats on the RK Tek package. It’s Christmas!
Do you have to do any tuning with the new head, or will the TPI naturally adjust to it and compensate.

Well, technically it needs an o2 sensor to adjust correctly for changes like a head or pipe but according to Kels it should run perfect with no adjustments needed.

Actually it's their 2 yr in production, plus didn't they claim it was in the works for 11 years. Jez, i could carve a tpi pumpkin in 11 years. I'm glad they actually have a working motorcycle, but they hardly reinvented the wheel. Think I'll stick with carbs or should i say lectrons for awhile.

Thats because the euro map made it richer.
